To mount the Divator visor, for Divator MkII, Spiromatic and Sari mask assemblies.
Made from robust, GRP (Nylon 12), the frame halves are easily fitted, inter-locating on key ways, to clamp the visor firmly in to the mask, using stainless steel screws (M3 x 25) {See item 2, on the diagram}
Changing visors at sea, or on site is no problem, taking around five minutes.
Tools needed: P2 x 100 Philip's screw-driver, small pry-bar (Flat blade screw-driver will do) and soapy water. Details are published in the Divator, User Manual, issued with every mask.
